Plus-one etiquette: set a clear policy

The common plus-one policies, how to say yours on the invitation, and kind wording for the guests who ask for an exception or bring someone you did not invite.

In this guide

The plus-one question rarely starts an argument by itself. The trouble comes from having no answer ready: one guest is told yes, another hears maybe, a third turns up with someone nobody expected, and you spend the week before the wedding explaining yourselves.

Choose a policy early, write it down in one sentence, and say it in the same words everywhere guests will look. This guide covers the usual policies, how to pick one, and kind wording for the awkward moments.

The four common policies

These are four policies you can adapt to your guest list. Choose one you can explain kindly and apply consistently.

  1. Named guests only. The invitation covers exactly the people named on it. Simplest to explain and the easiest on the budget.
  2. An unnamed plus-one for everyone. Every guest may bring someone. It is generous, and it adds up quickly.
  3. A plus-one for married, engaged or long-term partners. A common middle route. You decide where “long-term” starts, so decide it before anyone asks.
  4. No plus-ones at all. Everyone comes as themselves. It works best for small weddings where most guests already know each other.

Partners you know about should be invited by name whatever the policy. A plus-one rule is about guests you have not met, not about excluding someone’s fiancé or wife.

How to choose your plus-one policy

Start with the numbers your venue and caterer have given you, then work out what you can afford to be generous about. Every plus-one is another person to feed and seat, so it is a real line in the budget, not a courtesy that comes free.

Three questions settle most cases:

  • How big is the room? If the venue caps your numbers, named guests only may be the only policy that fits.
  • Will guests know anyone? A guest who will be sat among strangers is happier with company. A guest surrounded by friends from the same office does not need it.
  • Can you hold the line? A rule you will drop for your cousin but not for your colleague is not a rule. Pick the one you can apply to everyone.

It is fine to make one sensible exception, for example inviting every guest who is travelling a long way with a partner. State the exception as part of the policy so it reads as a rule, not a favour.

Say it twice, in the same words

Put the policy on the invitation and again on the page where guests reply. People read the invitation once, set it down, and answer later from the reply form. If only one of them carries the message, some guests will miss it. The same advice appears in wedding RSVP wording.

Named guests only, on the invitation
We have reserved two seats in your honour. Your invitation is addressed to the people named on the envelope.
Plus-one allowed, on the reply page
You are welcome to bring a guest. Please give their name when you reply.
Partners only
We are able to invite married, engaged and live-in partners. If your invitation names a guest, they are very welcome.

Asking for a name is useful in its own right. A named guest gets a place card, a meal choice and a seat, and you find out before the day that “my friend” is actually somebody’s ex.

Capping plus-ones and counting them

“A guest” is not the same as “anyone you like”. If you are allowing plus-ones, put a number on it, per guest rather than overall, and make sure the reply form respects it. Otherwise “and family” turns into five seats.

Keep a running count as replies arrive. A plus-one that has not been named yet is still a seat the caterer is counting, so give yourself a column on your guest list for it. It is also worth counting plus-ones separately from invited guests, because your caterer will eventually want one total, by a date that your RSVP deadline should sit well ahead of.

In JoinMe you set one plus-one limit for the whole invitation, from none up, and guests give each plus-one’s name when they reply. If your policy differs from guest to guest, invite each household with a personal link and a seat allowance of its own. That household can fill no more seats than you gave it, whatever the overall limit says. Each reply lands on your private manage page with its party size and names, so the headcount you send to the caterer is the one on your screen. See everything a wedding RSVP page includes.

When someone asks for an exception

It will happen, usually by text, usually in a friendly way. Answer quickly and kindly. Delay makes it harder, because the guest starts to read the silence as a maybe.

Lead with the reason, not the refusal. You are not punishing anyone: the room, the budget or the caterer’s numbers are what is fixed. Then end on how much you want them there.

Declining a plus-one
Thank you for asking. We have had to keep the list to the people named on the invitation, because of the size of the room. We would love to have you there and are sorry we cannot say yes to this one.
Saying yes to a partner you had not realised about
Thank you for telling us. We would be glad to have them join us. Please send their full name so we can add them to the list.
When a guest cannot come without someone
We understand, and we are sorry the plans do not fit. We will miss you on the day and would love to see you afterwards.

Whatever you decide, tell the next person who asks the same thing. Consistency matters more than the answer.

When a guest brings someone uninvited

A guest may have misunderstood the policy or overlooked it. In either case, the best moment to deal with an extra name is before the wedding, not at the door.

  1. Reply early and privately. If the reply form shows an extra name you did not allow, message the guest the same day.
  2. Offer a clear choice. Either the extra guest cannot come, or you can accommodate them and say what the new number is.
  3. Check with the caterer on the day. If someone does turn up, ask whether a place can be found within the room limit. Do not promise a seat or a meal until the venue and caterer have agreed.
  4. Hand the problem to someone else on the day. You should not be the one working this out in your wedding clothes. Give a trusted friend or relative the job.

If you can fit the extra guest, welcome them quietly. If you cannot, have your nominated helper explain the limit privately. You do not have to overturn a clear policy at the door.

Children and households

The envelope sets the expectation. “Mr and Mrs Okafor” invites two adults; “The Okafor family” invites everyone under that roof. Choose the form that matches your intent and be exact. Guests read addressing closely.

  • Write children’s names on the invitation if they are invited.
  • State “adults only” on the website, not only by omission.
  • Decide whether babies in arms count, and say so.
  • Ask each person in a household to be named separately when they reply.
  • Tell guests whether there will be a children’s meal, a sitter or a quiet room.
Adults only
We love your little ones, and we have planned an adults-only celebration. Thank you for helping us keep it that way.

If you are inviting only some children, such as relatives, say that it is a family decision and does not reflect on other guests. A short, even tone is enough. Over-explaining invites debate.

Questions people ask

Do I have to give every guest a plus-one?

No. A plus-one is a courtesy, not a rule. Whatever you choose, apply it consistently and say it plainly on the invitation and the reply page so no one is surprised.

Should engaged or married guests always be invited with their partner?

Yes, as a matter of courtesy, and by name. Partners you know about should be on the invitation, whatever your plus-one policy says about guests you have not met.

How do I say no to a plus-one without offending someone?

Give the practical reason, such as room size or the caterer’s numbers, thank them for asking, and say you would love to have them there. Reply quickly and treat everyone the same way.

Can I ask guests to name their plus-one?

Yes. A name lets you write the place card, record a meal choice and check the number. Ask for it on the reply form rather than chasing it by message later.
